I wonder whether this explicit install is actually needed at all.
Shouldn't the driver be installed via the APIC probing mechanism
automagically?
Only in case x86_init.irq.intr_mode_init is set appropriately. Today it is
a nop for Xen PV, but that can be changed. I'll have a look.
You could simply set that callback to default_setup_apic_routing() and
be done with it.
Doesn't work because XEN overrides it already. So sure, lets just go
with the solution you proposed. One more ugly or less in XEN/PV does not
really matter much :)
Let me grab this and put it into the right position in the queue.
